The "virtual LED" technology developed by 3M and designer Todd Bracher uses only one LED bulb to illuminate a large area by illuminating a series of fixed reflectors. These reflectors use a special 3M film that reflects more than 98% of incident light. In addition, 3M has specially designed directional reflection to reflect light from one reflector to another. Thus, in the case of only one hidden light source, the user appears to be the series of light-emitting of these reflectors.
Of course, a single LED produces limited light energy, so it can't be used to provide enough illumination for the entire room to perform delicate surgery, but the advantage is that only a handful of LED bulbs can be used with the reflectors that cover the walls. Provides amazing amounts of light with minimal energy consumption.
Todd Bracher is currently working on the project, and the engineering team's top priority is to reduce the cost of coating. This technology is expected to be put into mass production in a few years, and it is hopeful to change our indoor lighting.
Semiconductor Fuse And Ferrite
Fuse refers to an electric appliance that, when the current exceeds the specified value, melts the fuse and disconnects the circuit with the heat generated by itself.When the current exceeds the specified value for a period of time, the fuse melts and disconnects the circuit with the heat generated by the fuse itself.A current protector made from this principle.The fuse is widely used in high and low voltage power distribution system and control system as well as power equipment.
Ferrite is a metal oxide with ferrous magnetism.As far as electrical properties are concerned, the resistivity of ferrite is much larger than that of single metal or alloy magnetic materials, and it has higher dielectric properties.Ferrite magnetic energy also shows high permeability at high frequencies.As a result, ferrite has become a non-metallic magnetic material widely used in the field of high frequency and weak current.Due to the low ferrite magnetic energy stored in the unit volume, saturated magnetic induction strength (Bs) and low (usually only pure iron 1/3 ~ 1/5), and thus limits its higher requirements in the low-frequency magnetic energy density in the field of high voltage and high power applications.
